As you may recall, NFS Audio had created a room tweak wherein laser light of a certain frequency was used to make the air in the listening room more 'coherent' and thereby more effectively couple the speaker/air interface and improve sound quality.

Also, the more 'coherent air' in the room iteself becomes a better conductor of sound, with less 'air induced' distortion products added to the music signal once it leaves the speaker.

Refresher image...

If you look closely, you'll see how well it makes the speakers 'vanish!'

Now, the new part:

Any room tweak worth its salt should be able to improve the sound of live music as well as recorded music, so the 'coherent air' tweak has now been used in a live venue...

Without being too visually obtrusive, this tweak was demo'd for an audience at a live show. The artist is John Batdorf (of Batdorf and Rodney) playing a solo show in a room measuring about 30 feet by 65 feet...

The pics are from my iPhone, apologies for the low rez. However, even with a low rez picture you can plainly see how the sound was improved using the 'coherent air' tweak to tune the room.

Hey I see a potential flaw in the design!!!!The lasers are moving, so surely this affects the results on the room acoustics You can see that the angle of the laser points actually shifts between the two different photos.Explain that one away

Also looks like he is squinting/closing his eyes, is that a side affect of being dazzled by a laser or a benefit tweak

Quote:I more worried about the fact that it made the drummer disappear as well.

Being vaporized is definitely a negative side affect and I hope Buddha includes the caveat in his product brochure

Buddha, nice response as well.

CheersOrb

WARNING: This device uses a high powered laser. Staring directly into the beam may cause damage to eye tissue. Drummers may be at additional risk, and have been known to vaporize faster than when a dinner check arrrives.

Quote:If the light did not roam, it would create a coherency effect similar to Ethan's beloved comb filtering...with some parts of the room having coherent air and some not.

Priceless.

Kudos, Buddha!

Well, it's an interesting problem, you see, the coherence of the incoherent air creates an incoherence in the coherent light, which coheres the sound to the incoherent coherence, thereby showing that the vessel with the pestle has the pellet with the poison, and the chalice from the palace has the brew that is true.

But, please, people, do not drop the chalice from the palice, or we'll have to drag out the flagon with the dragon.

Can these possibly work, or does science disallow it? I am not trolling.

Coherent light, coherent air, coherent sound? Coherence by definition means that multiple signals have a constant phase relationship. For this to happen all signal sources must have a common reference.

Geez, it doth appear science has been disobeyed once again.

I suggest passing along your complaint to jj in the hope it will be brought up at the next Randi staff meeting. Or, you could have Elk check with his colleagues at the institute.

Quote:Demo'd the laser light tweak (LLT) for some people over the weekend.

I am stealing the comment, but one of the ladies quipped, "It seems like the speakers energize the room better."

Interesting, and spontaneous, description.

I like that word - especially when thinking about tweeter/room interaction. I was surprised she brought it up.

She also has one of the Supersymmetric Superstring Tweaks (SST) we made this past winter and was wearing it for the listening session.

I don't doubt it one bit. Shinning ordinary light (lamp or high beam flashlight) on cables and interconnects for 15 minutes before listening works quite well. Or flooding the room with light. (IIRC that was a Bob Crump suggestion.) It's possible coherent light might be even better.

Pop Quiz -- Pt 1. If a red laser light show was used, wouldn't that more or less replicate the Intelligent Chip for the case of a CD player? Pt. 2. How can the laser light show in the room affect the disc inside the CD player?

Aha so we do not need Buddha's expensive system, I get the same effect using torch lights!!!Buddha your trying to con us here in the same way we get an Oppo inside 3k+ players!Please confirm your system does not use multiple torch lights inside a snazzy box somehow simulating a laser light effect while costing 5x more And did you do a DBT ABX between a torch and your uber laser system?I appreciate its difficult to remove all tell signs as a disintegrating drummer sort of stands out

Oh and Geoff, probably the wittiest photo you used in awhile (Simple Jack), definitely a touche response.

What system did you test the "Intellegent Chip" on?

What equipment? What room size. What T60 profile? What noise floor? What early reflections? Enquiring minds want to know.

How would you test the chip? What system and type of room would you use? I'd be interested to know. I hope I'm not being presumptuous here - skeptics do test things sometimes, don't they?

Quote:Well, you make claims to how it works. So, you have tested it, right?

I'd have thought you'd insist any legitimate test must be performed by an independent third party. You must be slipping. If you don't believe a mfgr's claims, which is certainly your prerogative, it only stands to reason you wouldn't believe their test results, either, no?

Quote:I'm not making claims about it, I don't have to say anything to say about how I might test it.

Geez, I didn't see that coming. But you're the one who apparently thinks the claims are false. Are you saying you'd believe my test report? Or are you just trolling?

Quote:YOU are making substantive claims about it. Please detail precisely and in documentary form how you test it.

Thank you in advance, Geoff.

Haven't you been paying attention? If anyone does testing, it is audio reviewers or independent labs, but certainly not audio manufacturers. The only test I'm aware of that involved the Intelligent Chip - I mean other than many listening tests that were perfomed by senior audio press at CES 2005 and the HI Fi Show in UK the same year, as well as at the home of the Hi Fi News Editor and staff, was performed by a skeptical audiophile who took the Intelligent Chip to a metallurgy lab to have it examined under an electron microscope, presumably to determine the presence or absence of "quantum material" in the chip.

Now that I think about it, the 2 PhDs over at 6 Moons DID do some sort of testing of the chip and the Intelligent Box a couple years ago. I could dig up the review for you if you wish....

Really, then, how do you know it even works?

Surely you must have some kind of "product quality" assurance.

In order to have that, you must have a way to test something.

Your company, not somebody else.

What is it?

How do I know it works? Well, if you must know, I have ways to determine if a product works, well, most of the time, anyway, including direct and indirect measurement, listening tests and the use of multiple systems and listeners. In the peculiar case of the Teleportation Tweak, which is performed long-distance, it's problemmatic since I obviously can't do a direct test; however, I obtain corroborating testimony, as it were, from customers. Surprisingly consistent, unambiguous testimony, if I can be so bold.
